Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.
Helium is generally used; special spectrometers to detect helium leakage are designed.
Ethyl Mercaptane is C2H5SH. It is a sulphur containing organic compound. It is added into LPG so as to detect any leakage of LPG. The Pungent smell that comes from LPG is tht of ethyl mercaptane,otherwise LPG is an odourless gas.
Natural gas is odourless. Gas for domestic use - has chemicals added to create a smell, so leaks can be detected.

Not sure about chemical? But there are highly sensitivity alarm metres for detecting the leakage of liquid petroleum gas (LPG, butane, propane etc), and natural gas. One method I once used to find a leaking joint on a gas cooker was to apply washing-up liquid round the joints until a joint bubbling up pin-pointed the leak.
We use the IC1 555 in LPG gas detector to detect the leaking gases.
Cumbustible gasses in LPG (propane) cylinders have no odor, you cannot smell them. Gas producers add a perfume to the gas so that you can detect leaks with your sense of smell. These perfumes are gasses called Thiols (or Mercaptans) and contain sulphur, which is easily identifiable in tiny amounts by its pungent scent.

I have an LPG gas detector in my kitchen to detect any leaks from my appliances. Would I be able to install one in my basement? yes, detectors should be on every level
Mexico uses LPG.
